ABSTRACT:
Managing volatile storage of information, such as executable code within dynamic random access memory (DRAM) embedded within an application specific integrated circuit (ASIC), includes systematically checking the contents of the volatile memory during periods of extended inactivity. Volatile memory checking routines may be initiated on the basis of time, on the basis of a specific event, or on a combination of timing and event occurrences. If a specific error condition is detected, the device in which the volatile memory resides may be automatically reinitialized, so that the corrupt executable code is not used. The information management techniques may be extended to other types of semi-permanent memory i.e., memory that is susceptible to losses in the form of soft errors.
